CAGE FOR ANTIFRICTION-BEARINGS.

Specification of Letters Patent.

Patented Mar. 7, 1916.

' Application filed October 13, 1913. .Serial No. 794,798.

To all whom it may concern-.-

Be it known that I, EWALD HANUs, engineer, a subject of the King of Prussia, residing at No. 14 Treskowstrasse, Tegel, near Berlin, Germany, have invented certain new and useful Improvements in Cages for Antifriction-l3earings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to anti-friction bearings, and has reference more particularly to the spacing cage usually employed therein to maintain the rolling elements of the bearing in spaced relations between the casing members.

A common type of cage comprises two opposing rings, and intermediate connecting devices arranged at intervals between the rings, and affording between them, seats for the rolling elements.

.The aim of my invention is to produce a cage of this type which will possess such degree of fiexibility, that a uniform distribution of the abnormal loads and undue shocks to which the parts may be in'practice subjected will be assured, and the invention consists in so forming the connecting devices, and so attaching them to the two rings of the cage, that the rings will be permitted to yield resiliently in a circumferential direction relatively to each other.

The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings Figure 1 is an elevation of a cage with the balls therein, one of the rings being cut away to expose other parts to view. Fig. 2 is an edge view of the same partly in section. Fig. 3 is an elevation of one of the connecting devices detached. Fig. 4 is an edge view of the same.

Referring to the drawings, my improved cage comprises opposing rings a and b, which are provided at intervals with slots 5 9, etc., the purpose of which will presently appear. Arranged between the rings at in-.

tervals are a series of connecting devices, consistingeach of a tubular member d slit longitudinally as ate, so as to form a resilient or yielding structure. At opposite ends these members are provided with lips I" and f arranged respectively on opposite sides of the slit therein. and in the asseinblage of the members between the rings, and their connection thereto, the lips f are passed through the slots in ring a and bent down thereon, and the lips f are extended through the slots in ring 6 and-bent down thereon, with the result that the two rings will be firmly but resiliently connected together by said members. Thesides of the several connecting members are concaved or curved-inwardly as at '5 6 so as to conform to the external curvature of the rolling elements 0, which are inserted between the connecting members, by suflicient forcible pressure of the balls against the outer edges of the adjacent members, to cause them to yield circumferentially far enough to admit the balls. At their inner and outer sides the coniiecting members are curved to conform to the circumferential contour of the rings so that they will not project beyond the same. By reason of the fact that the connecting devices are individually resilient in a direction circumferentially of the ring, and by reason of the further fact that the said members are connected on opposite sides respectively with the two rings, the latter are elastically connected, and will be per mitted to yield resiliently relatively to each other in a circumferential direction, the walls of the slits e in such actions of the rings, approaching each other, and sepa-.

,form or construction of the parts ex ept in so far as such limitations are specied in the claims.

Having thus described my invention, what I claim and desire to secure .by Letters Patent is: v

1. A cage for antifriction bearings, sai cage comprising two opposing rings, and a series of intermediate connecting devices serving to space the rolling elements of the hearing, each of said connecting devices comprising two portions yieldable one relatively to the other in a direction circumferentially of the rings, one of said rings being connected to one only of the two portions of' each connecting device, and the other ring being connected only to the other portions of the connecting devices.

2. A cage for antifriction bearings, comprising opposing rings, and a series of intermediate connecting devices serving to space the rolling elements of the bearing, said devices consisting each of a tubular member having a longitudinal slit extending therethrough, the said members being connected at one end on one side of the slits therein with one ring, and being connected atthe other end on the other side of the slits therein with the other ring.

3. A cage for antifriction bearings, comprising opposing rings formed with slots,

.other ring.

same, and said member being provided at opposite ends'with lips located respectively on opposite sides of the slit, the lips at one end of said members engaging in the slots in one ring, and the lips on the other end of the members engaging in the slots inthe In testlmony whereof I have affi xed my signature-in presence of two witnesses.
